PROCESS FOR THE MANUFACTURE 0F PLATES 0R SLABS IMlTATING MARBLE.

To all whom it may concern: v

Be it known that I, OoTAvE DEVILLERS, a subject of the King of the Belgians, and a resident of J umet, Belgium, have invented ,a certain new and useful Process for the Manufacture of Plates or Slabs Imitating Marble, of which the following is a specification.

This invention has reference to a process for manufacturing multicolored sheets of glass having a rough surface for fixing them in place and which are made accordin to this process of covering with colored g ass. This process is carried out in such a manner that glass bubbles of one 'or more colors are blown so as to form a ball, the thickness of which does not exceed one-half millimeter and which when bursting forms scales of various shades. These fra ments of glass are sprinkled over a sheet 0 transparent glass, and it remains with the knowledge, taste, and craftiness of the workman to imitate in a perfoot manner the lines, &c., of the design. Be fore this sheet is introduced into the oven it must be covered with an enamel of a suitable color (this enamel may also bepoured over in a li uid state) which constitutes the back ing co or and fills up the empty spaces. In the oven the sheet of glass, scales, and ename'l fuse together, so that the colors mix together and form a natural-grain. As the scales are not completely fused, their edges and extremities constitute a rough surface forflxing the sheet in lace, so that the plates can be easily attached by means of any convenient cement to surfaces of all kinds.
